Our Renew / Cancel Index predicts potential renewal or cancellation for scripted broadcast primetime shows by the end of the 2010-11 season in May, 2011. (includes results from January 3-30, 2011):

Program Status Renew/ Cancel Index
Life Unexpected cancelled 0.73
Hellcats 🙂 🙂 🙂 🙂 0.94
90210 🙂 🙂 🙂 🙂 0.94
One Tree Hill 🙂 🙂 🙂 🙂 0.94
Gossip Girl 🙂 🙂 🙂 🙂 0.94
Nikita 🙂 🙂 🙂 🙂 1.14
Vampire Diaries :mrgreen: :mrgreen: :mrgreen: :mrgreen: :mrgreen: 1.66
Supernatural (F) :mrgreen: :mrgreen: :mrgreen: :mrgreen: :mrgreen:
Smallville (F) final season

There’s frequent chatter in our comments about how one or more members of the One Tree Hill cast has claimed this was the show’s last season. I wouldn’t know, I don’t follow, let alone trust, anything that cast members say in public. It could in fact turn out to be true, but if One Tree Hill is cancelled it will have to be some non-ratings reason like that, because it has the ratings for renewal.

The CW returned last week with what was to be a full week of new episodes, but Friday’s Supernatural and Smallville were delayed for repeats of Nikita and The Vampire Diaries. It matters little for next season though, as except for Life Unexpected and Smallville, all the CW shows still look likely to be renewed for next season.

Life Unexpected’s season (and to anyone but the craziest of fans, series) finale was January 18.

The Renew/Cancel Index is the ratio of a scripted show’s new episode adults 18-49 ratings relative to the new episode ratings of the other scripted shows on its own network. It’s calculated by dividing a show’s new episode Live+Same Day adults 18-49 average rating by the Live+Same Day new episode average of all the new scripted show episodes on the show’s own network. The network’s average ratings in the calculation are not time weighted (ex. hour long shows are not weighted twice what 30 minute shows are).

(F) -Fridays: Shows airing on Fridays were renewed with significantly lower than average Indexes.

How would the Renew / Cancel Index Have Done Predicting Last Season’s Scripted Show Fates? While the methods used have changed slightly from past seasons check out how the Renew / Cancel Index would have predicted renewals and cancellations from the 2009-10 broadcast television season.
